TELESCOE IC HOSE COUPLING.

Application filed May 25, 1927.1 Serial No. 194,162.

' This invention relates to a hose adapted to be connected with a dispensing apparatus for gasoline. V r I An object of the invention is the provision of a hose adjustable as to length in which a lower section telescopes over an upper succeeding section so that the lower section including the nozzle, will be of a sufficient cross sectional area that itwill permit the liquid flowingthrough the upper section to be discharged readily through the lower section without creating any back pressure.

ii furtherobject of the invention is the provision of a hose made of a plurality of telescoping sections with the sections nearer the discharge opening of successively greater cross sectional area than the preceding sections and in which means is provided to maintain the hose in substantially a straight line from the dispensing apparatus to the container wherein the liquid is dischar ed so that the liquid will more readily flow into the container and none will be maintained in the hose after the liquid has been dispensed.

A still further object of the invention is the provision of a gasoline hose formed of telescoping sections in which a spring or other retractive device is employed for maintaining the parts in telescoping relation while permitting ready adjustmentas to length of the hose.

This invention will be best understood from a consideration of the following de-' tailed description in view of the accompanying drawing forming a part of the specification; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure l is a view in perspective of a dispensing apparatus showing my gasoline hose attached thereto.

Figure 2 is a view in elevation and section showing a modified form of the invention.

Figure 3 is a fragmentarysectional view showing a detail of the connection between the spring and the dispensing apparatus.

Figure i shows a further modified form of the invention.

Referring more particularly to the'drawings, 1O designates a container of the usual type in which gasoline or other liquid to be dispensed is'adapted to be filled therein. The discharge spout 11 is connected with the container at its lower end through which the liquid is adapted to flow when the outlet valve is open for the purpose. Such spout has a universal connection as shown at 12 to which the pipe 13 is connected which maybe of metal or some flexible material. This pipe has a predetermined cross sectional area and is of such a length as to meet the needs when c0- operating with a section 14 of a hose to fill the tanks of automob les.

The section 14 is of greater diameter than the section 13 so that the section 13 is telescoped within section 14, the free end of the section 14 being provided with the outlet nozzle 15. The clearance between the two sections must be sufficiently restricted in order to prevent loss of fluid from the upper end of the section 14. However, thecross sectional area of the section must be sufliciently extensive to permit the ready discharge or" the fluid from the pipe 13 through the nozzle 15 without creating any back pressure of the-fluid in the'section 14. r

The section 13 has slidably mounted thereon a plurality of rings 1'? provided with eyes 17 adapted to receive avguiding and supporting wire or cable 18 which is controlled by a cable 19 and a reel 20. The reel is maintained under tension so that the section 14 of the hose may be maintained in any position relative to the section 13. RinglS" is secured to the section i l-at the upper end thereof, and the outer end of the cable 18 is attached to the eye 17 of said ring; The

lower ends of the rings are connected by a chain 21 which has one end secured at 22 to the upper or outer end of the section 13;

Referring more particularly to the modified form in Figure 3 a section of the hose is illustrated at 25 and connected with the universal joint 12. Embracing the section 25 is j tached. The outer free end of the section 28 is provided with a nozzle 15. In this construction the telescoping pipe 28 may be extended by reason of its slidable mounting on the pipe 25 and is prevented from being released from the section 25 by the coil spring 26 or other means. After the section 28 has beenreleased from its extended position the coil spring will return the section to its proper telescoping relation with the section 25. The clearance 29 between the sections 25 and 28 is sufficiently small to prevent ready dis charge of the liquid from the upper end of the section 28, the cross sectional area of which compared to section 25 is such that back pressure will never be created within section 28 so that the-fluid will not be discharged from the upper end of section 28.

Section 28 is made offie'xible material while section 25 may be made of rigid material but section 25 may be made also of the same material as section 28. The inner end of section 28 is sheared at an angle as shown at 24 to facilitate the movement of the end of said section through the spring 26.

Referring more particularly to Fig. 4, a further modified form is shown in a fragmentary manner in which the outer or telescoping section 30 receives the upper section 31- with the section 30 being maintained against loss from the section 31 either by means of a spring 34 or by means of a cable 7 as shown in Figure 1. The pipe or section 30 which carries a nozzle at its free end is formed of flexible material and carries clamping collar 32 having a toggle lever 33 formed in the'usual manner whereby when the toggle 1S operated in the proper manner the ring 32 will clamp the upper end of section 30 to section 31 and not only aid in preventing thedischarge of fluid from the upper end of section 30 but for locking the two sections in extended relation or for locking the fact that the hose is maintained substantially straight at all times, thereby preventing any accumulation of gasoline in any of the bent portions of the hose'when-the nozzle has been elevated sufiiciently. This construction a so provides for a longer life of the hose .5 5* utained substantially in a straight line thus eliminating the usual bend ing of the hose.

I claim 1'. A telescopic hose coupling formed of two sections, one of the sections being'telescopically received by the other section, means for supporting said one of the sections, and means for retaining the other section in operative relation with the first mentioned section, said last mentioned means including means for returning the sections tothe normal inoperative position after said first men tioned section has been moved outwardly from the second mentioned section.

2. A telescopic hose coupling formed of two sections, one of the sections being telescopically received by the other section,.with the second section being slidably mounted on the first section, means for supporting the first mentioned section, meansfor supporting the second section on the first section-while permitting sliding movement of the second section on the first section, said last men tioned means including means for returning the section to the normal inoperative position after said first mentioned section has been moved outwardly from the second mentioned section. l

3. A telescopic hose coupling formed of two sections, one section being slidably mounted on the other section, the first mentioned section being adapted to be projected outwardly from the second section andbeing of suificient cross sectional areaas compared to the second section topermit fluid to be readily discharged from said first section without creating backpressure in the said second section, and means for maintaining the sections of the hose in operative relation with each other, said last mentioned means including means for returning thesection to the normal inoperative position after said first mentioned section has been moved out wardly from the second mentioned section.
